Join server error, MIC failed

Hi all,
I am using Loraserver v 0.23.3 and Lora App Server v 0.17.1. My device join request causes error. I couldnt find any setting to set appeui. My other setting seems to be true. Lora server says:

level=info msg=“packet(s) collected” dev_eui=43…a1 gw_count=1 gw_macs=19…96 mtype=JoinRequest

The dev_eui in this message is same as my dev_eui setting. And I double cehcked it from packet decoder. So I am sure that the problem is not about byte order. Is there anybody who knows why this error is happening?

Error messae:

level=error msg=“processing rx packet error: join-request to join-server error: response error, code: MICFailed, description: invalid mic” data_base64=“ADJoAPB+1bNwoXEJyYQY40Mfd5eAyeA=”

What can be the problem? How can I know what appeui/appkey/mic is calculated and it is not paired with the device message’s?

Best regards
